Setting Auto reset ("D Hold") time for DTMF doesn't work as expected

[traeu]

Using the option "Auto reset time (s) (D Hold)" under "DTMF Settings" in CHIRP results in unexpected behavior:
Entering a single digit in the allowed range (5-9) results in the device displaying "0s" at D Hold menu (51/60). This option normally can't be selected and results in endless open squelch after a DTMF call.
Entering a two-digit number in the allowed range (10-60) results in the first digit being used. That means, setting 60s in CHIRP results in 6s on the device.

Additionally, if I set this value to 60s in CHIRP, save the config-file, close CHIRP and re-open the config, the value gets set to 6s.
